Re: Opencockpits USBLCD Card Displays
Jack,
The pot is just a convenient way of varying the current thru the backlight to adjust brightness. It has a built in resistor and was designed to run off 5v.
if you want a better way of adjusting the brightness then i suggest you build Mikes PWM LED dimmer he featured on this site, gives better control of this brightness.
Les
P.S You are using the wiper(usually the center but check) and one other terminal as a variable resistor between the cathode and ground of the
LED.

Re: Opencockpits USBLCD Card Displays
Hi Les... Another question.
The manual for my LCD Display says infact that Pin 15 is 5V, not 16, and vice-versa for GND. Does this mean I'll have to swap the wiring round for the OC manual? A test with a multimeter also confirms that pins 15 & 16 are the inverse of what the OC Manual says.

Re: Opencockpits USBLCD Card Displays
Jack,
You can configure your module either way, just look at the datasheet. You will have to look at which way its configured, then its a simple as
changing your wiring to suit.

Re: Opencockpits USBLCD Card Displays
In that case, will it stil lwork? The OC Manual specifically reccommends dot-matrix, no mention of pcb fittings.
One comforting thing is though, that both Opencockpits and Maplin manuls both have exact 14 pins arranged in the exact same order on a table.
Is it okay if I solder to the LCD Display, connect this to an IDC style connector, then swap the wires to match USBLCD Card, then connect up?

Re: Opencockpits USBLCD Card Displays
Hi,
Opencockpits docs does have some errors, probably due to traslation(they specify a Dot Matrix display but they mean LCD). When it comes to their LCD card you only have to make sure that the connections on the LCD module connect to the same on the O/C module. How you do this depends on how the connections are terminated on your lcd module. Some have pads to which you have to solder wires, others have IDC connectors.
Hope this helps. Feel free to ask if i help any further.
Les
